Comment out an incorrect lock assertion. The swap code path in uvm_aio_aiodone() is not holding the corresponding page lock and shouldn't as long as anons are locked inside uvm_page_unbusy() to handle the PG_RELEASED case. Reported by Ralf Horstmann on bugs@ |

Grab the kernel lock in uvm_wxcheck() when aborting the process kern.wxabort=1 logs and kills programs after W^X violations. At least sigexit() -> coredump() as well as the non-atomic increment of ps_wxcounter require protection, so grab the big lock for the entire block. This is part of the effort to unlock mmap(2)'s MAP_ANON case. Feedback mvs claudio kettenis deraadt OK kettenis |

Fix and re-enable active scans on iwm(4) and iwx(4). Ensure that we supply the access point's DTIM period to firmware after an active scan, as soon as the next beacon arrives. This prevents the problems which prompted us to keep active scans disabled in our drivers. Problem debugged and patch by zxystd from the OpenIntelWireless project. I made some tweaks regarding TIM parsing, which were reviewed by zxystd. Johannes Berg from Intel has confirmed to me via IRC that firmware will misbehave if running with a zero DTIM period.
